摘要： A method for fabricating an LCD includes: providing a substrate with a thin film transistor (TFT) part defined thereon; forming a metallic film for a gate electrode on the substrate; etching the metallic film through a first printing process to form a gate electrode; sequentially forming a gate insulating layer, a semiconductor layer, and a metallic film for source and drain electrodes on the substrate; selectively etching the metallic film for source and drain electrodes, the semiconductor layer and the gate insulating layer through a second printing process to form a gate insulating layer pattern, a preliminary active pattern and a metallic film pattern which are sequentially stacked such that the gate insulating layer pattern is over-etched from the side of the preliminary active pattern; forming an insulating layer on the substrate with the metallic film pattern; etching the insulating layer to expose the metallic film pattern; forming a transparent conductive film on the metallic film pattern and a remaining insulating film; and selectively etching the transparent conductive film, the metallic film pattern, the preliminary active pattern to form an active pattern, a source electrode, a drain electrode, and a pixel electrode connected with the drain electrode.

The TFT array substrate includes gate and data lines insulatively crossing each other to define a pixel area, a TFT provided at the crossing of the gate and data lines, a passivation film protecting the TFT, a pixel electrode partially overlapped by the TFT, a gate pad connected to the gate line, and a data pad connected to the data line. The gate line, the gate and data pads, and the pixel electrode include a transparent conductive material. A gate metal material is on the transparent conductive material where the TFT partially overlaps the pixel electrode. The passivation film over the gate and data pads is removed to expose the transparent conductive material included within the gate and data pads.
